Question
The following C program has a buffer overflow vulnerability. Your tasks are as follows: Explain what the project does. Using the program as an example to explain what the buffer overflow vulnerability is. Your answers should contain no more than 200 words. Note: You need to draw memory stacks to demonstrate your understanding. Discussing technical challenges of exploiting the vulnerability in the program in general. stack.c This program has a buffer overflow vulnerability."/ int bof(char "str) ( char buffer[24]: strcpy(buffer, str) return 1; int main(int argc, char "argv) ( char str 517): FILE badfile; badfile fopen("badfile", "r fread (str, sizeof(char), 517, badfile): bof (str): return 1;Explanation / Answer
In that we have one buffer and one original storage called str with 24 bytes and 517 bytes respectively.here we are open the badfile in read mode.find the size of str in badfile we know already it has 517 bytes of maximum size.and now that str is copied into buffer for temporary by function bof(str).here the str size is exceeds the buffer size so the total data is not getting buffered ,hre the buffer overflow is taking place.but in program each time one buffer is created with 24 bytes so the data of str is written into the buffer without buffer overflow vulnerability.because This is the program for bufferoverflow vulnerability
